Stabilization of cloud cavitation instabilities using Cylindrical Cavitating-bubble Generators (CCGs)
TL;DR: In this article, the authors proposed a passive control method called Cylindrical Cavitating-bubble Generators (CCGs) on the surface of a benchmark hydrofoil and analyzed the effects of this passive controller on the dynamics of the unsteady cloud cavitation.

Eddies Stream, and Convergence Zones in Turbulent Flows
TL;DR: In this article, a set of objective criteria were found which describe regions in which the streamlines circulate, converge, or diverge, and form high streams of high velocity flow.

A new modelling of cavitating flows : a numerical study of unsteady cavitation on a hydrofoil section
TL;DR: In this paper, a bubble two-phase flow (BTF) model is proposed to explain the interaction between viscous effects including vortices and cavitation bubbles, which treats the inside and outside of a cavity as one continuum by regarding the cavity as a compressible viscous fluid whose density changes greatly.
